Application filed November 3, 1818. Serial No. 129,377.

To all whom it may concern.

Be it known that I, BEH'III". F. DELK, a citizen of the lhiited States, residin at Macon. in the county of Bibh and tatc of Georgia. have invented a new and useful D-Tlandle-Finishing Machine, of which the following is a specification.

The present invention appertains generall to wood working machines and aims to provide a machine for finishing D-handles, such as used for shovels, spades and similar implements, it being the object of the invention to finish the handles mechanically, to save labor and expense. and to do the work as perfect if not better than done by hand,

and employing only unskilled labor.

The machine embodies in its essential features, novel means for rounding the inside of the grip of the handle. novel means for chamfering the inner edges'of and novel means for chamfering the outer edges of the handle. and novel means for receiving, centering and moving the handle for the several operations.

\Vith the foregoing and other objects in low which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can he made within the scope of what is claimed without departing from the spirit of the invention.

In carrying out the invention, the machine embodies asuitable frame 1, and a. verticalhandle carrying shaft 2 is slidahle in the frame intermediate the sides thereof and adjacent to the forward end thereof. A forwardly projecting fork 3 has its shank secured upon the upper end of the shaft 2 and provides a V-shaped member 4 for re ceiving and centering the shank 5 of the handle which projects upwardly, the handle being placed m the machine with the grip lowermost. Secured to the lower terminal of the shaft 2 is a forwardly projecting bracket 6 upon which the ip of the handle 7 isseatable with the ban 1c in a longitudinal vertical plane end the frame has upstanding centering guides 8 at the opposite.

sides of the bracket 6 to receive said bracket wurd movrn'ieut thereof.

when the shaft 2 is in its lowermost position, and to bring the handle 7 into the proper longitudinal, vertical done when the handle is inserted with the iimrlict G lowered between the guides 8.

As :1 means For holding the handle 7 in proper position upon the bracket 6, the-elm lt 2 has a 'fm'wardly projecting spur 9 im mediately above the butt end of the bracket 6, to engage the rear end. of the gri of the handle, and the lorarltel 6 is prorhlzid with upstanding guide lugs l0 and 1.1 near its free end and in front of the handle, a longituiliiml rod 12 being slidable through the lugs ill--11 and having a spur 18 at its rear end to engage the forward end of the handle grip. A lever 13 having a relatively long depending arm is fulcrumed, as at 14:, to the free end of the brucket. 6 and has it short iqim'nrdly projectingarni provided with an aperture 13 through which the forward. terminal of the rod 12 extends. A (fillltll wire expansion spring 15 surrounds. the rod 12 between the lug 11 and upper arm of the lever 13, to swing said upper arm forwardly and the lower arm of the lever rearwardly, whereby the upper arm will grip the rod 12 and prevent the {on The rod 12 is spring pressed to move forwardly by means of a coiled wire expansion spring 16 surrounding it and confined between the hip; 10 and a collar ii secured upon the rod between the lugs 10 and 11. When the rod 1: is moved toward the left, as seen in 22, against the tension of the spring 16, the upper arm of the lever 13 in engaging the rod can ,reaiflil'y swing toward the left against the tension of thespring 15, said. lever being moved in engagement with the rod 12 hr its sup-ring 1 Consequently, the upper urni oi the lever 13 in being swung toward the right by the spring 15 will grip or bind the rod lizl to prevent the movement thereof touaril the right unless the lower arm of the lever 13 is swung toward the right to swing the upper arm thereof to ward the left whereby to remove the corners of the upper arm of the lever 13 formed by the aperture 13 from the rod 12. Said corners when engaged with the rod 12 by the influence of the spring 15 will grip said rod and prevent the movement thereof to Ward, the right, since when the rod tends to move toward the right under the influence of spring- 16, this will only cause the lever 13 to more tightly grip the rod.

The machine is rovided with means for automatically moving the rod 12 into engagement with the handle and for releasing it at the proper time. Thus, a transverse shaft 19 is journaled in bearings 20 carried by the forward end of the frame, and is operated by means ofa worm wheel 21 carried by one end thereof and meshing with.

forward end of the rod 27.

a special worm 22 secured upon a longitudinal shaft carried by the frame at the left side tllereoli As seen in Fig. 2, the worm 22 is of special form, whereby instead of imparting n slow continuous rotary moie ment to the worm wheel 21, it imparts a relatively lust intermittent motion thereto, which is preferable to correspondingly ro tate the shaft 15). An inverted U-shaped driving member 24 has its ends fulcrumed to the frame at .25, with the intermed ate portion of said member 24 in position to more rcarwardly against the forward end 01' the rod 12 when the handle carrier or shaft "3 is in its lowermost or handle re ceiving position. Cams 26 are secured upon the shaft 19 to bear against the limbs of the menihcr 2d, and the shaft 19 is so rotated that the cams 26 are brought into operation for winging the member 21 rearwardly at the proper time. W'hen the member 24 is i'oi'emlrent-wholly to more the rod 12 like- Win 3 the spur 1H is brought into cngagw ment with the handle 7. thus moving the handle into engagement with the spur 9, and this will hrin the handle into the proper rmsitii'm longitudinelly of the bracket 3, the spurs 9 and 18 having stops at their bases for contacting with the handle to hold the handle in proper place. The shaft 2 is feathered to the frame or is of non'circular cross section to prevent the rotation thereof, whereby the handle is constrained to move in, the proper vertical line. The upper arm or grip of the lever 13 permits the rod 12 to move rearwardly, but has a gripping or binding action on the rod to revent the forward movement thereof nu er the tension of the spring 16 which tends to release the rod or its spur 18 from the handle. Thus. when the rod 12 moved rearwardly, it is held in engagement with the handle by the gripping lever 13.

The means for moving the lever 13 to release its hold or grip on the rod 12, embodies a longitudinal push rod 27 sliduble in guides 28 carried by the frame below the bracket 6, said rod 27 being moved rear wardly by a spring 29, and being located in such a position that when the shaft 2 is in its lowermost position, the lower end of the lever 13 depends immediately in front of the The rod 27 is moved forwardly at the proper time by means of a cam disk 30 carried by the forward end of a lower longitudinal shaft 31 j ournalcd to the lower portion of the frame, said disk 30 carrying a cam 32 which 211-.

gages the rear end of the rod 27 and moves- 1t forwardly at the time'that it is desired to release the handle. hen the rod 27 is moved forwardly, it strikes the lower end of the lever 13 and swings the lower arm of said lever forwardly, thereby swinging the upper form or grip of the lever rearwnrdly,

9 ,link 37 with 'shaft '45 meshes which will release the rod 1 2, so that the spring 16 is brought into play for moving the rod 12 forwardly. This releases the spur 18 from the handle, so that the handle can be removed. The lever 13 is moved into gripping engagement with the rod 12 under the influence of the spring 15, and the spring 16 holds the rod 12 in released ,position until again driven rearwardly, by the driving member 24.

Theshaft 31 is driven from a transverse;

driving shaft 33 journaled to the frame ad jacent to the rear end thereof, and connected by a suitable reduction gear with the shaft 31. Thus, the shaft 33 can be rotated at a relatively high speed, While the shaft 31 rotates at a slower velocity, the successive operations being carried out while the shaft 31 makes one revolution. As a suitable reduction gear between the shafts 31 and 33, a

worm 4.1 is secured upon the shaft 33 and meshes with a worm wheel -42 secured upon the shaft 3 The shaft 33 is operated by an engine, motor or other prime mover, and for this purpose a pulley wheel 34 is mounted loosely upon one terminal of the driving shaft 33, and is adapted to be belted or otherwise connected with the pririNrover. A suitable clutch 35 is employed for connecting the pulley wheel and shaft 33, and is controlled by a lever 36 fulcrumed to the frame at the left side thereof, at which side the pulley wheel 34 is located, and the lower free end of the lever 36 is connected by a an arm 38 of a longitudinal rock shaft 39 carried by the left side of the frame near the lower end of its legs. The forward end of the rock shaft 39 has a treadle 40 extending in front of the frame, and is adapted to be depressed by the operator for operating the clutch 35. The clutch 35 is thus readily operated for bringing the shaft 33 into and out of operation, the pulley wheel 34 rotating continuously durinr the operation of the machine. The sha 23 is driven from the driving shaft 33,

and for this purpose, a gear wheel 43 is socured to the rear end of the shaft 23 and meshes with a gear wheel 44 secured upon a longitudinal shaft 45 journaled within the frame adjacent to the left side thereof. A bevel gear 46 secured to the rear end of the with a bevel gear 47 secured upon the driving shaft 33. The worm 22 and Worm wheel 2.1 provide a reduction gear whereby the shaft 19 rotates once for each revolution of the shaft 31.

A device (illustrated in ployed for raising an lowering the handle carrier or shaft 2. T is device embodies a cam 48 secured upon the shaft 31 between the ends of the frame and said cam has an inner concentric portion 49, a cam portion 50 extending outwardly-from the portion 49 to an outer-concentric portion -51, and a.

Fig. 18) is emscrew 69 is threaded cam portion 52 extending inwardly from the portion 51 to the portion 49, to complete the outline of the cam. A lever 53 is fulcrumcd at one end, as at 54, to the frame adjacent to the left side thereof, and projects inwardly and downwardly to engage the cam 48, said lever 53 havin rollers 55 and 5G to ride upon the cam. A link 57 connects the lever 53 and shaft 2, and is provided with an adjusting turn buckle 57'. As the cum 4-8 rotates, the roller in engaging the inner concentric portion 49 will hold the shaft 2 stationary in lowermost position, and as the portion 50 engages the rollers 55 and 56, the she ft 2 is raised quickly to its uppermost position, and is held stationary in up per nost position during the engagement of the rollers with the outer concentric portion 511 The rollers in engaging the cam portion 52 permit the lever 53 to swing do\\'nwardly; whereby the shaft 2 is moved dou'nwardly in the proper manner for the suc ('essivc actions of the cutters on the handle.

The first cutting o lerution is to finish lho inside of the handle grip when the handle in its uppermost posil ion. This is accomplished by the devices which will be doscrihed presently.

There are two of these devices, one being a right hand one-and the other the left hand one, being disposed at the right and left hand sides of the frnme at the opposite sides of the,hund1e when in position. Each of those devices embodies a flat carriage 5S slidable transversely toward and away from the handle upon a shelf 59-01 the frame, there being two spaced shelyes for the two carriages 58. Each carriage 58 is normally moved outwardly toward fthe side of the frame, and for this purose, the carriage has an upstanding post F60 connected by a coiled wire retractile spring (31 with a hearing bracket 62 through which a short vertical shaft 63 is journaled at the respective side of the frame. The shaft 63 carries a horizontal cam disk 64 havin an outstanding cam 64, the cams 64' of t e two devices being so located that they are brought into operation in succession. Each carriage 58 has a roller 65 at its outer end bearing against. the edge of the respective cam disk 64 under the action of the spring 61. This roller 65 is mounted upon an adjustable bracket 66 having a longitudinal slot 67 through which a clamping bolt 68 extends, said bolt being carried by the carriage, and when loosened, permitting the bracket 66 to be adjusted longitudinally of itself and to various angles for properly positioning the roller 65, to control the movement of the carriage 58 by the cam disk 64. To prevent the displacement of the roller 65 by the pressure of the cam 64' thereagainst,,..an adjusting through an upstanding lug 70 with which the carriage is provided, 130

and bears against the ln'nchctjl'iti to prevent the inward movement thereof. The screw 69 also facilitates the adjustment of the bracket tit \Vhcn the cam (i-l engages the roller 65 it serves to pu h the carriage 5S vinwardly to bring the respective grip-finish lug cutter into operation.

In order 10 c mate the rain disks til, they are provided upon their upper surfaces, with teeth 71 tn'ovidingworm wheels which mesh with worms 7'2 secured upon the terminals of a transverse shaft 73 journaled in the bearing brackets 62 and other suitable bearings of the frame. A sprocket wheel 7% is secured upon the shaft 7 3, and a sprocket chain 75 extends around the s rocket Wllflfil 7-l and over a sprocket whee 76 rotatable loosely upon a transverse rock shaft 77 journalcd to the frame at the top thereof. From the sprocket wheel 76, the sprocket chain 75 extends downwardly under a sprocket wheel 78 secured upon the driving shaft 33, and that run of the chain between the sprocket wheels Tl and 78 passes over an idler sprocket wheel 79 carried by the frame. The shaft 78 is thus connected to tho driving shaft to be operated thcrcljiy, and the worms 7) in engaging the teeth 71 of the cam disks 64, providc'a proper reduction gearing so that the cam disks (i4 rotate once for each revolution of the shaft 31.

Each carriage 58 has a transverse uide channel 80 disposed longitudinally o the ,machine, and in whicha plate or supplemental carriage 81 is slidable forwardly and rcarwardly when loosened for purpose of adjustment. The plate 81 has longitudinal. slots 82 receiving clamping bolts 83 carried by the carriage 58, to clamp the plate 81 in place. and adjusting screws 84- are threaded downwardly through the plate 81 adjacent the corners thereof. and seat upon the carriage 58 for raising the corner portions of the plate 81 for purpose of adjustment, the bolts 83 being loosened while the screws 84; are adjusted and being tightened after the screws are adjusted, to clamp the plate 81 in place. The plate 81 can be adjusted forwardly and rcarwardly and can be tilted. in various directions by properly adjusting; the screws 84 and sliding the plate 81 upon the carriage. The adjustment of the plate 81 is used for adjusting the corrcspomliug grip-finishing cutter.

Seated upon the plate 8.1 is the base of an angular bracket 85 pivotally mounted upon a vertical clamping bolt 86 carried by the plate 81, said bolt 86 serving as a pivot for the bracket 85 and also scrvin to clamp said bracket upon the plate 81. T e bracket 85 has an outwardly projecting tail piece or extension 87 disposed between a pair of adjusting screws 88 threaded through upstanding lugs 89 carried by the plate 81, said screws 88 clamping the tail piece 87 thercbetween, and serving to adjust the bracket 85 angularly about a vertical axis. The inner end of the bracket 85 has an upstanding portion 90 to the inner side of which. a luinger or arm 91 is pivoted. The portion 90 carries an inwardly projecting shouldered bolt or pivot 92 u on which the upper end of the hanger 91 is pivoted, the hanger 91 thus being swingablc forwardly and rearwardly about a transverse axis. The plane in which the hanger 91 moves is determined by the angular adjustment of the bracket 85, and the adjustment of the plate 81. The gripfinishing cutter is carricd by the lower end of the hanger 91, and for this purpose, a flat circular head or block 93 has one face resting against the inner side of the lower end portion of the hanger 81, and i pivoted and clamped to said hanger 91 by means of a bolt. 94 ex tending loosely through the hanger 91 and threaded into the head 93. When the bolt 91 is loosened, the head 93 can be adjusted angularly about a substantially transverse axis, and when the bolt 94 is tightened, the head 93 is clamped against the hanger 91 to hold it firmly against the hanger. The head 93 has an upstanding tail piece or extension. 95 engaged by a pair of opposite adjusting screws 96 threaded through in wardly projecting lugs 97 carried by the hanger 91. By adjust1n the screws 96, the angular position of the lead 93 can be ad justed accurately, and the screws 96 also serve to prevent the accidental displacement of the head 93.

There are two grip'finishing cutters 98, one right hand and one left hand, and they are carried by the respective heads 93 of the two hai'igers 91. Each cutter 98 has opposite cutting edges and is curved to properly finish the respective half of the inside of the handle grip, as suggested in Fig. 8, and the cutter 98 is provided at one end with a shank 99 of circular cross section fitting ad'ustably in an aperture in the head 93 below the pivot bolt 94. The shank 99 is. held adjustably in its aperture by means of a. set screw 100 carried bythe head 93, the set screw when loosened permitting ol the longitudinal and angular adjustment of the shank 99 to correspondingly adjust the'cutter 98. The cutter 98 is curved upwardly and inwardly from the shank 99 to enter the opening of the handle and trim the corresponding half of the inside of the grip.

101 to which coupling members 102 are pivoted' by substantially vertical pivots, and links 10:1 are pivoted to the members 102 by substantially transverse horizontal pivots, whereby to provide universal joints between the hangers and links 103. The rear ends of the links 103 are connected by similar universal joints 104 with a depending arm 105 secured to the rock shaft 77. The links 103 have turn buckles 106 for purpose of justment, to regulate the throw or stro e of the levers 91. The rock shaft 77 is oscillated by means of an arm 107 sacured to the right hand end thereof, and having a longitudinal slot 108 adjustaloiy receiving a pivot 109 to which the upper end of a pitman 110 is connected. The low .1 end of said pitman is connected to a W118i? pin 111 outstanding from a crank disk 112 secured to the right hand end of the driving shaft 33. The rotation of the wrist pin 111 reciproeates the pitman 110 to oscillate the arm 107 and rock shaft 77, and the links 103 are thus reciprocated for oscillating the hangers 91 and their cutters 98 relatively fast, there being no reduction aring between the driving shaft 33 an the cutters 98.

A pair of right and left hand devices is provided for chamfering or beveling the outer edges of the handle at the opposite sides thereof during the downward movement of the handle from its uppermost position. These devices embody guides 113 carricd by the frame 1 at theopposite sides of the line of movement of the handle, and transverse rods 11 1 are slidable longitudinally in the guides 113, there being a pair of said rods at each side, and the rods of each pair being parallel with one another. The rods are spaced apart longitudinally of the frame and are located in the same horizontal plane. An upwardly projecting oscillating frame 115 has its lower end mounted slidably and swingably upon each rod.

111, said frames 115 being arranged in pairs at the opposite sides and being swingable forwardly and rearwardly about transverse axes. Coiled Wire retractile springs 116 connect the frames 115 and guides 113 thereby to yieldably move the frames 115 inwardly, and the rods 114 carry collars 117 to limit the inward movement of the frames 115 and to carry said frames outwardly with the rods 114 when they are so moved. The remote ends of the rods 114 are pivotally connected with upwardly projecting arms 118 at the opposite sides secured upon longitudinal rock shafts 119 journaled to the 0pposite sides of the frame. Inwardly projecting arms 120 are secured to said rock shafts 119, and their adjacent free ends are connected together by a linlg121, so that said arms are oscillated simul aneously. ram 122 is carried by the cam disk 30 or shaft 31 to depress the arms 120 at the proper time to bring the frizzers into operation. The arms 120 are normally raised by coiled wire retraetile springs 123 connecting them and the frame 1, whereby the arms 115 are normally swung outwardly to move the rods 114 likewise, and to carry the frames 115 outwardly to inoperative posi tion.

The upper free ends of the frames 115 of each pair have brackets 121 projecting toward one another, and in which transverse frizzer shafts 125 are journaled, said shafts projecting inwardly and carrying the frizacre or rotatable chamfering cutters at their inner ends.

The frizzers are of special construction. there being four of them, two at each side. Thus, each shaft 125 is provided with a disk or flat head 126 at its inner end, and a cutter 127 rests snugly against the face of the disk 126 and has the radial tapered cutting edges 1.28. A washer 129 rests against the hub of the cutter 127, and a clamping screw 130 extends through the washer 129 and central aperture of the cutter 127 and takes into the disk 126 to clamp the cutter and washer in place. The washer 129 provides a roller to roll along the edge portion of the handle, while the face of the disk 126 is adjacent to the respective side or face of the handle.

In order to cause the frizzers to properly follow the outer edges of the handle during the downward movement. of the handle, the frames 115 are oscillated properly through the medium of a suitably designed cam. Thus, the forward frames 115 are connected by links or rods 131 with upwardly project ing arms 132 secured upon a transverse rock shaft 141 journalcd to the main frame 1 at the rear thereof. The rear frames 115 are connected by similar links or rods 133 with downwardly projecting arms 132 secured to the rock shaft 141. whereby the rock shaft141 in being oscillated will swing the forward and rear frames 115 toward and away from one another. In order to operate the rock shaft 141, an arm 135 is se cured thereto, and is provided with a. roller 136 engaging the edge of a cam 137 secured upona transverse shaft 140 journaled' to the frame 1 below the rock shaft 77. The cain 137 has a concentric portion 138 which in swinging the lever or arm 135 will so move the links 131 and 133, to separate the forward and rear frames 115, whereby to remove the frizzers from the path of the handle to keep the frizzers out of operation until the proper time. The earn 137 has a cam portion 139 which when followed by the roller 136 will permit the shaft 141 to rock properly to cause the frames 115 to swing toward one another so that the frizzers follow the outer edges of the handle 7. The roller 136 is held against the cam l3? by means of coiled Wire rel raetilu springs l rl eonnreling the forward lramca H5 Hid the main frame l. The arlm ll2-l3: have longitudinal slurs l l!

The cutters 177 of each pair (toinplenieni one another to conform to the shape of the inner edge of the handle, and. the strokes of the cutters 177 can be properly regulated by the various adj astinents provided.

The arms 15; are oscillated transversely at the propel time, and for this purpose, coupling members 179 arr "Ol'lIlLfittNl by longitudinal pivots 11.80 will; lho upper ends of the arms 16: and links i831 arreoaneoted by vorlioal pivots 1.82 with the members 179, to provide universal joint: mason the Links 18 and arms 1 33. Bald links 181 have turn buckles 183 for ailjnting the lengths tliereof, to control the oscillation of the various arms 163. The remote emfls oighe two pairs with the clutch hubs 190. Retracti 193 connect the levers 192 and frame 1 for fiicriim'ed, as at 204,

lower end is connected by a pin and slot.

oilinks 181 are ivoted, as at 184, to bands or eccentric straps 185 embracing cams or eccentrics 186 secured upon longitudinal shafts 187 jouriialed to the o posite sides of the frame. The cams 186 0 each pair are in reversed positions, Whereb the arms 163 of each pair are oscillated in opposite directions, to bring the knife cutters 177 of each pair into operation in succession rather than simultaneously. This enables each cutter 177 at each side to complete its cut Without interference from the companion cutter. The arms 163 oscillate in planes at an acute angle relatively to one another, whereby the cutters 177 move into engagement with the handle along converging lines, and said cuttersprovide overlapping cuts, which necessitates the successive operationthereof.

In order to rotate the shafts 187, gear wheels 188 are secured thereto adjacent their rear ends and mesh with gear wheels 189 rotatable loosely upon the shafts 45 and 150 at the opposite sides of the frame, said shafts 45 and 150 being connected by the bevel. gears with the driving shaft 33. The gear wheels 189 have clutch hubs 190 006 erable with clutch members 191 feathere upon the shafts 45 and 150, and upwardly projeetin g levers 192 are fulcrumed to the frame and are connected by suitable swivel joints with the clutch members 191 to move said clutch members into and out of en agem'ent e springs normally piikling the levers 192 to remove the clutch embers 191 from the clutch hubs 190. The levers 192 are connected by links 194 with cam operated levers 196, universal joints 195 being providedbetween the links 194 and lever 196. The levers 196 are operated at the proper time by cams 197 carried by a cam disk 197 secured to the rear end of the shaft 31. When the levers 196 are swun by the cams 197, the links 194 are pulle to swing the levers 192, thus bringing the clutch members 191 into engagement with the clutch hubs 190. to thereby connect the cam or eccentric shafts 187 with the driving shaft 33. When the shafts 187 are rotated, the cams 186 being rotated will oscillate the arms 163 thus bringing the cutters 177 into operation. Said cutters swing through arcs having the pivots 16 1 as "centers, and the cutters are movable in wardly and downwardly to provide a. chamfering cut.

The cam disk 197 also operates the clutch member 159 at the proper time, a cam 198 being carried by the dis 197 and being engageable with a roller 199 carried by a transverse sliding rod 200 movable in guides 201 carried by the rear end of the frame. A vertical lever 202 has its upper end fulto the frame 1, and its most position,

connection, as at 203, with the rod 200. The lever 202 is 205, to the clutch member 159. When the roller 199 is moved by the cam 198, the rod 200 is slid to the right, as seen in Fig. 4, thereby swinging the lever 202 to brin the clutch member l 59into en agement wit the friction cone 160. The c utch member 159 acts as a pulley wheel and is connected by a belt 206 to a pulley wheel 207 secured upon the driving shaft 33, so that when the clutch member 159 is moved into engagement with the friction cone 160, the shaft 158 will be rotated, 'to operate the frizzers.

Before taking up the operation of the machine, reference is had to Figs. 20 and 21, to point out the work done by the machine. The outside a of the grip 7' of the handle 7 is finished before the handle is introduced in the machine, and the two halves oand b are finished in succession by the grip-finishing cutteis 98, it beingnoted that the ip 7' is curved longitudinally and is of CIICUlaI cross section. The second finishingoperation resides in the chamferin as at d, of the outside edges or corners of the handle 7, which is done by the frizzers. cutting operation resides in the chamfering of the inner edges or corners, as at e, which is done by the chamfering cutters 177.

- The operation of the machine is as follows:

Assumiii that the shaft 2 is in its lowerwith the rod 12 in released position, the handle which is in the ma chine, if there is one. can be readily re moved, and the next handle brought into place. During the ierval of changin handles, the treadle 40 can be operated for disconnecting the pulley 34 from the drivin shaft 33, so that the various mechanisms W51 be at a standstill. The handle 7 is placed on the bracket 6, being broughtinto the proper longitudinal vertical plane by the guides 8 between which the handle is introduced. and the upstanding shank 5 being brought into the member 4 will be centered properly. The machine is then set in motion by the operation of the treadle 40, and the cams 26 then swin the drivin member 24 against the rod 1 to push sa d rod rearwardly and force the spur 18 into the handle 7, said handle being thereby also forced into engagement with the spur 9. This will clamp and hold-"the handle in'proper position upon the bracket 6, the gripping lever 13 holding the rod 12 in engagement with the handle. .The cam 48 now raises the The third pivoted between its ends, as at,

lever 53 to raise the shaft 2 to its uppermost position, and the shaft 2 is held for a. sufit cient period of time in tioii for the operation of permost position, the cams 64: push the carriages 58 inwardly in succession. Thus,

friction cone 160, so that the frizzers stop 64 then moves the other carriage inwardly ho bring its cutter 98 into operation for finishing the remaining half of the inside of of the inside of the handle grip 7'. Said ",oarriage 58 is then retracted by the respecgtive spring 61 after the camfi has passed the respective roller 65, and the other cam the handle grip.

.the cam 48.

After the grip is thus finished, the shaft 2 is fed downwardly due to the travel of the rollers of the lever 33 on the portion 52 of The handle is thus gradually lowered for the operation of the frizzers thereon Thus, during the lowering ofthe handle, the cam 122 de resses the arms 120 and slides the rods nrmwardl so that the springs 116 slide the frames 115 inwardly. This brings the frizzers into operative position, and at the same time the cam 198 moves'the roller 199 to bring the clutch memher 159 into engagement with the friction cone 160, thus operating the frizzers, and the cam 137 is brought to a position so that the springs 134 move the links 131 rearwardl-y to rock the shaft 141. This rocking movement of the shaft 141 serves to swing the forward and rear frames 115 toward one another radually at first and then with a final acce eratinginovemenl'. so that the frizzers follow the Enter ed es of the handle. The fra'ines 115 are thus rought into operative position to bring the frizzers into en-- agementiwith the outer corners or edges of t e handle 7 and as the handle is moved downwardly, thefrizzers are moved toward one another tolell'ow the edges of the hair-- dle, and the friz'zers being rotated will cham for or bevel-said edges. When the handle is lowered to bring the 'frizzers adjacent to the shank 5, the cam 137 swings the arm or 1 ,aeo,344

one cutter 1.77 of each pair is moved into the opening of the handle to cut away the rcsprctn'iportion of the inner edge or corner of the handle, and then the other cute lei-s 177 are brought into operation to complcte the chamfering or beveling of the inner edges of the handle. When the cutters 177 are returned to normal position, the cams 19? release the levers 196, and the clutch members 191 are then moved to released positions by the springs 193. The handle is now in its finished condition, ready for removal.

When the handle is thus finished, the cam pushes the push rod 37 forwardly, to swing the lower arm of the lever 13 for wardly, thereby causing said lever to release the rod 12, which will ill; once spring ing in the cost of operations in finishing the edges of the hand and the inside of the grip, and the various cutters are mounted for proper operation upon the handle and can be adjusted to a nieety for properly carrying out their functions. Various means can be used for bringing the several cutters into operation other than those herein disclos'ed, and other changes and alterations can he made within the scope of the appended claims, without departing from the spirit of the invention.

The cam 122 is also moved to let the arms swing upwardly to pull the rods 114 andframes 115 outwardly. When the frizzers are removed from the handle, the cam 198 also releases the roller 199, so that the friction clutch member; 159 disengages the rotating.
